Yes you will have a problem. You need the correct model of flash. The connections to the cameras are different

I just bought this for my D80. It works perfectly fine. If you zoom in to the max then the built-in flash will cast a shadow (the lens itself is in the way) because you are so close to the object, in that case you need external lighting. No other 'issues' (this will happen regardless of what macrolens you use, so it isnt really an issue) that I have seen, great lens.

This 58 Macro fits on to a 52MM lens. I just did it with my Canon Rebel 300D, an older first model of the Rebel series; which is what I am collecting at this time. Thank you for your kindness.

Yes I received mine a week ago and the lens crashes into the filter; not just in macro but any time the camera struggles to focus. Reading online apparently the lens can protrude a little when focusing causing the crash. I think I got a lemon so the adapter ring is going back.Update: nevermind I'm just a dumbass. I had accidentally assembled it in the wrong order. All is good and focus works fine. Since it is possible to put together backwards it makes me wonder how many of the focus reports are just user error.

I would love to hear about a review of this sigma vs the canon flashes. as i have a sx20 and i need a large flash for large dim rooms.

It would be helpfull if you told us what triggers and what camera u are using. I bought Pixel King Wireless iTTL triggers for NIkon and they do not work with my Sigma EF-530-DG-Super... so you see it is not only about the Flash...

I don't really know, I own Nikon's, but you may find this link helpful. You can always check Canon support to be sure. Good luck. http://www.dpreview.com/forums/thread/2212757

If it doesn't specify canon mount it's probably a sigma mount. That's what happened to me. Then when I exchsnged it they didn't have the nikon mount at the same price. Had to reorder from another store.

They have a Nikon version so that version should. I shoot Canon so I can't confirm.

I'm sorry to hear of your problem. Unfortunately, I'm not familiar with the D3100 model. I believe both my model camera's Flash "F" in the display for fault or something in "M"anual setting but still fire. What lens are you using? This might explain the whole problem. Also you might try attaching them both to the camera body and unscrewing lens first then remove just the ring from the camera body. I will seriously try to help you as much as possible.

Honestly, I can't answer an Nikon questions. I have a Canon and haven't had a problem. There was a part that I had to place between the camera and the lens; if you do not have that (Nikon or Canon connector/adapter?), that may be what is causing you a problem.

Hey Donna......we had the same problem so returned it. My husband ordered a Nikon lense and has encouraged others not to buy other brands. They just dont work on the Nikon. Hope this helps.

With the Canon version the camera reports f/2.8 at every distance including macro. There is some light loss at macro distances but don't worry about this, the exposure meter compensates automatically. With the Nikon version you may see the loss of light at close distances reflected as the camera actually reporting a smaller aperture. Either way it's completely normal for a macro lens to have some loss of light at very close distances. All macro lenses are the same in this regard. Don't worry about it!

The nikon version supports i-TTL/D-TTL (where metering is done through the camera system), while the canon version supports E-TTL (Evaluative through the Lens exposure) II. Copy and paste the following link for a better explanation: http://photonotes.org/articles/eos-flash/. It's probably a proprietary software difference in the exposure calculations, but from what I understand the ringlights are otherwise identical, albeit probably not interchangeable.

I had purchased the wrong flash to work with my camera so returned it. Sorry I couldn't help you. By George

Really I don't know, because i bought the Adapter for a Nikon camera with a 60 mm macro, and it work perfect. Maybe you could need a ring adapter for your canon.
